I put money into 16.5 Mhash two and half months ago, and am selling most of my gear now. 3-4 months ago the profits were good, you were practically guaranteed at least .1200 per Mhash. Now you are lucky if you get anything above .0058. I have sold most of my gear now at a slight loss which doesn't bother me. I came to a realization that I should have played the arbitrage game, which would have made me WAY WAY more than what mining could have ever brought in. I sadly couldnt do that because it took so long for BitStamp to approve me...very slow process. The only people that are benefiting are those that began mining years ago, which by now have paid for all of their hardware and made money. Also people that pay very little for electricity, especially in colder climates which dont have to use AC to cool down their hardware.
ASICs are coming guys, I didnt want to accept it myself. They are pricey however, but sure do save on power. Problem is, is that a solid ASIC unit thats in development that does 9-30Mhash is costing almost the same amount in video cards. It will still take you a long time to break even, even if you are paying less for electric.
